FOLDABLE STOOL.

Specification of Iietters Patent.

Patented July 22, 1919.

-Application filedEebruary 6, 1918. Serial No. 215,576.

.Be it' known that I, FREDERICK HAGNER, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Foldable Stools, of whichthe following is a specification. 1

This invention relates to new and useful improvements in a foldable stool.

The object of the invention is to provide a stool of the character described primarily designed for the purpose of attachment to a sewing machine, and which may be collapsed into a compact form and swung into position underneath the top of the machine and out of the way, when not in use. However, the stool is adapted for use in connection with a'desk, table or other similar article of furniture.

Another object of the invention resides in the provision of a novel means for locking the stool in position for use, said means preventing the premature or accidental collapse of the stool. 1

"Another feature of the invention resides in the provision of means through which the stool may be attached to a machine, desk, table or other object, said means permitting the stool to swing clear of the object to which it is attached, for use, and also permitting said stool to be collapsed and swing under the machine, desk,'or table, and when in said last mentioned positionholding the feet of the stool clear of the floor, thereby permitting the article of furniture to be moved about the floor without obstruction.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangement of parts and use, anexample of which is given in this specification, and illustrated in the accompanying drawings wherein Figure 1, shows a side view of the stool attached to a sewing machine.

Fig. 2, shows a rear view thereof.

Figs. 3 and 4, show enlarged fragmentary views of the lower end of the foldable leg employed.

Figs. 5 and 6, show plan and side views of the link, whereby the stool is attached to the machine, and

Figs. 7 and 8, show the stationary bearing attached to the machine to which one end of the link is pivoted.

Referring now more particularly to the HAYES ened by the arch 4, the central part of which is formed into a transverse bar 5.

The numeral 6 designates the stool bot tom, which is preferably, circular in form. Th s bottom is secured to an arch formed of the diverging legs 7, 7, which are connected near their apex by a cross bar 8. To the apex of said arch, formed by the legs 7, 7, the upper end of the leg 9 is pivoted, said three legs diverging at an equal angle from the stool bottom when the stool is in use. A- link 10 is pivoted at one end to the leg 9, and its underside is provided with a notch 11, which receives the cross bar 8, thereby locking the leg 9 in a fixed position, relative to the stool bottom, and to the other legs when the stool is in use. The stool is provided with a back 12, which is secured to the upper ends of the supports 13, 13. These supports are hinged at their lower ends to suitable bearings 14, 14, carried by the stool bottom, and the lower end of one of said supports has anextension 15, to the free end of which one end of the rod 16 is pivoted. The other end of this rod is provided with a laterally extending pin 17, which extends through an oblong bearing 18, in the free end of the link 10, and whose free end is formed into a head 20, thus preventing the detachment of said pin from said head.

As above explained, when the stool is in use, the legs 7 and 9 are locked in relative position by means of the link 10, and will remain so looked as long as the back of the stool is in a vertical position. When it is desired to collapse the stool, the back 12 and supports 13, 13, are folded down upon the stool bottom, thus operating through the extension 15, and the rod 16 to lift the link 10 and disengage the notch 11 from the cross bar 8. The leg 9 may be then moved back into transverse alinement with the leg 7.

A vertical bearing 21 is clamped to one of the front legs 2 by means of a clamp 22, of any desired form, and this bearing is given an outward and forward inclination for a reason to be hereinafter explained. A link 23 is provided, whose inner end has a pin 24, which fits in the bearing 21 and the outer end of said link is formed into an open ring 25, provided to receive the lower end of the leg 9. Said lower end has a finger 26 pro]ecting therefrom and above said finger is notched on each side forming a narrow neck 27, said neck being provided to receive the open space of said ring 26,

so that in applying the link 23 to the leg 9, the open ring may be passed over the neck 27, and then moved downwardly, the open space of the ring permitting its passage below the finger 26. The link is then swung around a one-half turn and said finger will prevent' its accidental detachment from the leg. Adjacent the pin 24, there is a catch 28 on the under side of the link 23, which engages an opposing shallow notch 29 in the upper end of the bearing 21. This catch assists in holding the stool in position, relative to the machine, when collapsed, but is easily released from its notch when it is desired to use the stool. The inner end of the link 28 is enlarged into a disk-like form having a segment, of one edge, cut away, forming the arcuate notch 30, and the shoulders 31, 31, and a pin 32 projects upwardly from the bearing 21 into said notch, against which said shoulders contact to limit the range of movement of the link 23.

lVhen it is desired to collapse the stool, the back is folded down, as hereinbefore eX- plained, and the legs 7, 7, are brought into alinement with the leg 9, the link 23 is then swung around into the position shown in dotted lines in Fig. 1.

As the link is swung around, its outer end will be gradually elevated by reason of the inclination of the bearing 21, so as to hold the lower ends of the legs clear of the floor and the stool bottom 6 engages over and rests upon the transverse bar 5, and is partially sustained thereby, so that said locking means when the back is folded down to the said bottom.

2. A stool including a bottom, a back hinged thereto, so as to be capable of being folded down onto said bottom, supporting legs pivoted relative to each other and capable of being brought into alineinent, means for locking said legs in fixed position to each other,. said means being operatively connected with said back,- so as to be released when the back is folded down to the stool bottom.

3. A stool formed of a bottom, supporting legs fixed thereto, a supporting leg pivoted thereto, a locking mechanism whereby the pivoted leg may belocked in a fixed position relative to the fixed legs, a back pivoted relative to'said bottom and means actuated by said back, when folded down onto said bottom through which said look. ing mechanism is released. 7

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
